It seems a Critical Update (KB978542) can cause problems with Windows Mail (WM) in Windows 7: Windows Mail crippled by KB978542
The update is applicable to both XP, and 7.
gallicbear, it would be helpful if you could tell us:
- If your win 7 is 32 or 64bit.
- Are XP, and 7 set up as dual booting systems on one machine or do you have two separate machines, and WM is causing problems on one or the other or both.
- When you get time this will help in seeing, and filling out your System Specs: System Info - See Your System Specs
If it is dual I suspect the Windows Live Mail (WLM) program that is shipped with 7 is in conflict with the legacy WM program, and if koolkat's SFC
suggestion does not help I have seen where uninstalling WLM from the 7OS can help.

I would restart your machine after the uninstall.
If that does not help I found some interesting thoughts here, including manually patching a certain .dll file, and a registry fix. If you would like to explore these further, but are unsure how to proceed please post back: How to enable Windows Mail app in Windows 7 - TechSpot Tutorials
As to why this just started to happen after you had it running for two years, and after a possible two year old update is difficult to fathom. Something changed or was added, possibly Windows Updates.
There is also some feedback concerning the Calendar feature becoming corrupt.
You may want to take a look in the Event Viewer
Specifically; Event Viewer >Windows Logs >Application
see if there are ESENT errors that indicate access denied: ESENT event IDs 1000, 1202, 412, and 454 are logged repeatedly in the Application log
If any pertain to WM or WLM please copy and paste error report in your reply.
